Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and more specifically, to a flow guide structure for a heating tube. Background Technology

[0002] In the field of heating equipment technology, the heating element is a core component, and its heating efficiency and stability directly affect the overall performance of the equipment. Traditional heating element structures typically heat the water inside the element directly, but this design has several significant problems.

[0003] First, traditional heating elements have a large internal space, holding a significant amount of cold water. This results in relatively low heating efficiency in the initial stages of heating due to the high specific heat capacity of water. This inefficient heating method is particularly inadequate when rapid heating to higher temperatures is required.

[0004] Secondly, when the water inside the heating element is heated to boiling, the water flow can easily become turbulent due to the large space inside the element. This not only affects the uniformity of heating but may also lead to unstable outlet water temperature. In extreme cases, this turbulent water flow may even cause safety hazards, such as localized overheating or dry burning.

[0005] In addition, during the heating process, the heat distribution on the surface of the heating element may be uneven due to the direct contact between the guide tube and the inner wall of the heating element. This uneven heating can easily lead to localized damage or dry burning of the heating element, thereby shortening its service life. Utility Model Content

[0006] The purpose of this invention is to provide a flow guide structure for a heating element, in order to solve the problems mentioned in the background art, such as the large internal space of traditional heating elements, which contain a lot of cold water, resulting in relatively low heating efficiency in the initial stage of heating due to the large specific heat capacity of water.

[0007] To achieve the above objectives, this utility model provides a flow guide structure for a heating element, including a housing, with a water outlet at one end of the housing and a water inlet at the other end. An inner flow guide tube is disposed inside the housing, and a heating element is sleeved on the outer side of the inner flow guide tube. A water channel is provided between the inner wall of the heating element and the outer wall of the inner flow guide tube. An inner tube sealing plug is installed at the end of the inner flow guide tube, and a cross-shaped flow divider is provided on the outer wall of the inner tube sealing plug.

[0008] Preferably, the water outlet includes a water outlet cover, a first sealing plug is installed in the middle of the inner side of the water outlet cover, the water outlet cover is locked and fixed to the end of the housing by a first locking bolt, a water outlet pipe is installed in the middle of the water outlet cover, a through hole is provided in the middle of the first sealing plug, and one end of the water outlet pipe communicates with the through hole.

[0009] Preferably, the water inlet includes a water inlet cover, a second sealing plug is installed in the middle of the inner side of the water inlet cover, the water inlet cover is locked and fixed to the end of the housing by a second locking bolt, a water inlet pipe is installed in the middle of the water inlet cover, a through hole is provided in the middle of the second sealing plug, and one end of the water inlet pipe communicates with the through hole.

[0010] Preferably, both ends of the heating element are locked and fixed inside the housing by clamping rings.

[0011] Preferably, two sets of electrode holders are installed on one outer wall of the housing, with the outer side of the electrode holder connected to a power source and the inner side connected to a heating element.

[0012] Preferably, the inner wall of the heating element is uniformly provided with several annular grooves.

[0013] Preferably, the outer ends of the diverter plates at both ends of the inner guide tube are respectively locked at the middle through holes of the first sealing plug and the second sealing plug.

[0014] Preferably, both the first and second sealing plugs are made of rubber material, and their outer walls are provided with several annular protrusions.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the flow channel structure of this heating element, an inner flow channel is set inside the shell, and the heating element is sleeved outside the inner flow channel, forming an independent water channel. This design allows water to flow along the outside of the heating element, reducing the unit heating water volume and thus improving heating efficiency. Especially when rapid heating to higher temperatures is required, this structure can significantly shorten the heating time.

[0017] The design of the inner guide tube makes the water flow more orderly and reduces turbulence. When the water is heated to boiling, the relatively small water channel space allows for smoother venting and a more stable water output. This helps improve the overall performance of the equipment and reduces safety hazards caused by turbulent water flow.

[0018] There is no direct contact between the inner guide tube and the heating element. Furthermore, the uniform annular grooves formed between the inner wall of the heating element and the guide tube help distribute water flow more evenly, preventing air trapping and resulting in more uniform heating of the heating element's surface. This design effectively reduces the risk of localized damage or dry burning caused by uneven surface heating of the heating element, thus extending its service life. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a flow guide tube structure for a heating element, such as... Figures 1-6As shown, the device includes a housing 1, with a water outlet 2 at one end and a water inlet 3 at the other. Inside the housing 1, a guide tube 11 is installed, and a heating element 12 is fitted around the outer side of the guide tube 11. A water channel 15 is formed between the inner wall of the heating element 12 and the outer wall of the guide tube 11. An inner tube sealing plug 111 is installed at the end of the guide tube 11, and a cross-shaped flow divider 112 is provided on the outer wall of the inner tube sealing plug 111. By cleverly placing the guide tube 11 inside the housing 1 and fitting the heating element 12 around it, an independent water channel 15 is formed. This structural design allows water to flow orderly along the water channel 15 between the heating element 12 and the guide tube 11, effectively improving the guidance and stability of the water flow. Meanwhile, the inner tube sealing plug 111 installed at the end of the inner guide tube 11 and the cross-shaped diversion plate 112 on its outer wall further ensure the uniform distribution and smooth flow of water, avoiding turbulence and local overheating during the heating process. This guide tube structure not only improves heating efficiency but also enhances the stability and safety of the equipment, bringing new solutions and technological advancements to the field of heating equipment.

[0029] In this embodiment, the water outlet 2 includes a water outlet cover 21. A first sealing plug 22 is installed in the middle of the inner side of the water outlet cover 21. The water outlet cover 21 is locked and fixed to the end of the housing 1 by a first locking bolt 23. A water outlet pipe 24 is installed in the middle of the water outlet cover 21. A through hole is provided in the middle of the first sealing plug 22, and one end of the water outlet pipe 24 communicates with the through hole. This design ensures a tight connection between the water outlet 2 and the housing 1, preventing water leakage. The water outlet pipe 24 installed in the middle of the water outlet cover 21 communicates with the through hole in the middle of the first sealing plug 22, allowing the heated water to flow out smoothly, improving the water output efficiency and stability of the equipment.

[0030] Specifically, the water inlet 3 includes a water inlet cover 31, with a second sealing plug 32 installed in the center of the inner side of the water inlet cover 31. The water inlet cover 31 is locked and fixed to the end of the housing 1 by a second locking bolt 33. A water inlet pipe 34 is installed in the center of the water inlet cover 31, and a through hole is provided in the center of the second sealing plug 32. One end of the water inlet pipe 34 communicates with the through hole. This structure is similar to that of the water outlet 2, ensuring a tight connection between the water inlet 3 and the housing 1 and smooth water flow. The water inlet pipe 34 installed in the center of the water inlet cover 31 communicates with the through hole in the center of the second sealing plug 32, allowing cold water to accurately enter the water channel 15, providing a stable water source for the heating process.

[0031] Furthermore, both ends of the heating element 12 are locked and fixed inside the housing 1 by clamping rings 13. This fixing method is simple and reliable, ensuring the stability of the heating element 12 during the heating process and preventing displacement or loosening caused by water flow impact or temperature changes, thereby improving the safety and service life of the equipment.

[0032] Furthermore, two sets of electrode holders 14 are installed on one outer wall of the housing 1. The outer side of the electrode holder 14 is connected to the power supply, and the inner side is connected to the heating element 12. This design allows the power supply to be easily connected to the heating element 12, providing a stable power supply for the heating process. At the same time, the installation position of the electrode holder 14 is reasonable, avoiding direct contact with water flow and improving the safety of the equipment.

[0033] Furthermore, the inner wall of the heating element 12 is uniformly provided with several annular grooves. These grooves increase the contact area between the water flow and the inner wall of the heating element 12, thereby improving heating efficiency. At the same time, the groove design also helps to ensure uniform distribution and smooth flow of water, reducing water flow turbulence and localized overheating.

[0034] Furthermore, the outer ends of the diverter plates 112 at both ends of the inner guide tube 11 are respectively engaged at the middle through holes of the first sealing plug 22 and the second sealing plug 32. This engagement method ensures the stable installation of the diverter plates 112 and prevents them from shifting or falling off under the impact of water flow. The design of the diverter plates 112 helps to achieve uniform distribution and guidance of water flow, thereby improving the heating efficiency and stability of the equipment.

[0035] Furthermore, both the first sealing plug 22 and the second sealing plug 32 are made of rubber material, and their outer walls are provided with several annular protrusions. The rubber material has good sealing properties and elasticity, allowing it to fit tightly between the end of the housing 1 and the end of the inner guide tube 11, preventing water leakage. The protrusions increase the friction between the sealing plug and the housing 1 or the inner guide tube 11, improving the stability of the sealing plug and preventing it from loosening or falling off during use.

[0036] In use, the guide tube structure of the heating element of this utility model allows cold water to enter the device first through the water inlet 3. The water inlet 3 includes a water inlet cover 31, and a water inlet pipe 34 is installed in the middle of the water inlet cover 31. The water inlet pipe 34 is connected to the through hole in the middle of the second sealing plug 32. When cold water flows into the water inlet pipe 34, it passes through the through hole of the second sealing plug 32 and enters the water channel 15 between the guide tube 11 and the heating element 12 inside the housing 1.

[0037] Water flows orderly within the water channel 15 between the inner wall of the heating element 12 and the outer wall of the inner guide tube 11. The inner wall of the heating element 12 is uniformly provided with several annular grooves. These grooves increase the contact area between the water flow and the inner wall of the heating element 12, allowing the water to more fully absorb the heat generated by the heating element 12, thereby improving heating efficiency. Simultaneously, the inner tube sealing plug 111 installed at the end of the inner guide tube 11 and the cross-shaped diverter plate 112 on its outer wall ensure uniform water distribution and smooth flow. The design of the diverter plate 112 helps maintain orderly water flow during heating, avoiding turbulent flow and localized overheating.

[0038] Once the water is heated to the required temperature, it continues to flow along the waterway 15 and eventually reaches the outlet 2. The outlet 2 includes an outlet cover 21, with an outlet pipe 24 installed in the middle of the outlet cover 21. The outlet pipe 24 communicates with the through hole in the middle of the first sealing plug 22. The heated water flows through the through hole of the first sealing plug 22, enters the outlet pipe 24, and then flows smoothly out of the equipment for user use.

[0039] The two ends of the heating element 12 are locked and fixed inside the housing 1 by clamping rings 13, ensuring the stability of the heating element 12 during the heating process. This fixing method is simple and reliable, preventing displacement or loosening caused by water flow impact or temperature changes. Two sets of electrode holders 14 are installed on one outer wall of the housing 1. The outer side of the electrode holder 14 is connected to the power supply, and the inner side is connected to the heating element 12. This design allows the power supply to be easily connected to the heating element 12, providing a stable power supply for the heating process. At the same time, the installation position of the electrode holder 14 is reasonable, avoiding direct contact with water flow and improving the safety of the equipment.

[0040] Both the first sealing plug 22 and the second sealing plug 32 are made of rubber material, and their outer walls are provided with several annular protrusions. The rubber material has good sealing properties and elasticity, allowing it to fit tightly between the end of the housing 1 and the end of the inner guide tube 11, preventing water leakage. The protrusions increase the friction between the sealing plug and the housing 1 or the inner guide tube 11, improving the stability of the sealing plug and preventing it from loosening or falling off during use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
